My invention provides a new method of eradicating noxious weeds and cultivatmf land and is especially designed for the efadi-" The steel rods A A and between rodsFA and the shaft 12.

' shaft 12.

rated by collars 17 as shown cation of sowthistle.

I attain these objects by the mechanism illustrated in the accompanying drawings in whith- Fig. 1 shows, the to view of the machine.

Fig. 2 shows, the si eelevation ofthe ,machine.

Fig. 3 is an end view of thecylinder with the end casting removed to show the details.

Fig. 4 is the cross-sectional side view of the cylinder showing details.

I Similar letters refer to similar parts,- throughout the several views.

Referring to the drawings:

1 and 2 are two frames-con a common revolving shaft 3 permitting frame 2 to be tilted to different positions by means of the lever 4 on the shaft 5, both ends of which are connected with the'ends of frame 2 so as to permit its tiltin 6 and. 7. are similar cogged wheels on sha t 3 which are connected by chains 8 and 9 respectively, with the simi ar cogged wheels 10 and 11 respectively on shaft 12. 13 is the eradicator and cultivator in the form of a cylinder rigid on The cylinder 13 consists of two metal ends 14 and 15,- which are connected by two sets of rods marked A and B respectively. .are an equal distance apartconnecting the two cylinder ends at similar points on their circumferences. The steel rods B are placed parallel to rods 16 are tooth castings, rotating on the rods A and placed so that all the teeth are sepaon Fi 'res 3 and 4. The teeth 16 are placed on t e rods A so that the teeth on any rod are placed opposite collars on the preceding rod. Each tooth casting projects inward toward the shaft 12 a little beyond .the rod B-corre+ spending to'the red A on which the tooth is located. In this wayjthe rods B serve asstops' for the inner projections of the tooth castings holding them against-further "rotation.

ends of the tooth castings 16 to thecollars 17 opposite them on the preceding rods A,

thus tending to keep the inner ends-of the teeth, close up against the rods B.

19 is a pul ey'on the shaft 3 to which the powe'r'can be applied from a stationary en- 'gine on the.

machine for the purpose of driving the cylinder 13. If the power pulling the machine is tobe the power drivin the cylinder also, it will have to be applie to the shaft 3 by means of large traction wheels rigid on the ends of said shaft.

In operationthe whole machine is drawn I forward in the direction marked F while the cylinder 13 is driven in the direction indicated by the arrows. The frame 2 can be tilted so. that the teeth 16 will enter the soil to the desired depth. Should the'teeth I encounter any obstructions such as stones, stumps, etc., they (the teeth) will rotate on the rods A so as to pass over the obstructions, when the strained springs 18 will pull them back into position again. As the teeth pass through the soil, the soil is very finely cultivated. At the same time, by virtue of the combing action of the teeth, the runningroots of the sowthistle, or other weeds, are completely eradicated and cast upon the surface of the ground free from any clinging soil. I

What I claim as my invention and desire to secure by Letters Patent is: I In a combination weed eradicator and cultivator, a cylinder comprising two metal ends, rigid on a shaft, which ends'are connected at similar points on their circumferences. by a set of steel rods placed equidistantfromeach other and on which rods are fulcrumed teeth separated bycollars which a'ro connected by heavy springs to the inner projections. of the tooth castings oppo-.- rods so as to holdthe innerprojectionso the eeth close against an inner set of steel rods, si 'lar and parallel to the outer set first mentioned, 'and placed between and in line with the outer set'of rods and the cylinder shaft so as to hold the tooth castings against further rotation.
